Answer:
The last table is a probability distribution.
Step-by-step explanation:
This problem is solved by applying probabilities definition, which is the positive quotient between possible events and all events.
However, the important thing here is that probabilities never can be negative, they can go from 0 to 1, that's it. So, all tables that have negative numbers, means that they have negative "probabilities", which is impossible, that means that they are no probabilities.
Therefore, the right table is the last one, because it contains positive numbers, indicating possible probabilities.
